Abstract

This study aims to analyze the potential of basil seed simplicia in feed to improve histomorphometric and muscle damage of catfish due to exposure to PS microplastics. This study is an experimental type using a Completely Randomized Design (CRD) with five treatments, namely K (0 mg/L PS microplastic + 0% basil seed simplicia), KP (0 mg/L PS microplastic + 2% basil seed simplicia), KN (100 mg/L PS microplastic + 0% basil seed simplicia), P1 (100 mg/L PS microplastic + 2% basil seed simplicia), P2 (100 mg/L PS microplastic + 4% basil seed simplicia). Microplastic exposure was carried out on 125 catfish for 15 days, the parameters observed included myofiber diameter, myofiber area, degeneration, and muscle cell necrosis. The results showed that exposure to PS microplastics significantly increased the diameter and area of ​​myofibers and reduced degeneration and necrosis of catfish muscle cells (P<0.05). The administration of 2% basil seed simplicia (P1) in the feed was able to increase the diameter and area of ​​myofibers and reduce the level of degeneration and necrosis significantly compared to KN, while the administration of 4% basil seed simplicia (P2) showed lower effectiveness. The conclusion of this study shows that 2% basil seed simplicia (P1) has the potential to improve histomorphometrics and muscle damage in catfish due to exposure to polystyrene microplastics.

Abstract

This study aimed to determine students’ retention levels before and after the use of the PlantNet application and to analyze the use of the PlantNet application on students’ retention in biology learning at SMA Negeri 1 Aek Natas. This research employed a quantitative approach described descriptively. The research subjects consisted of 61 tenth-grade students, comprising 31 students from class X2 and 30 students from class X3. The research instruments included a questionnaire on the use of the PlantNet application and a student retention test covering short-term retention, long-term retention, and conceptual understanding. Data were analyzed using percentage analysis to determine the achievement category of each indicator.The results showed that the use of the PlantNet application was categorized as very good, with ease of use reaching 91.7% and usefulness in learning reaching 88.8%. In terms of student retention, short-term retention reached 83.4%, long-term retention reached 84.2%, and conceptual understanding reached 84.6%, all of which were categorized as good. These findings indicate that the PlantNet application is not only easy to use and beneficial in biology learning but also supports students’ memory and enhances their conceptual understanding of the learning material. Therefore, the use of the PlantNet application has the potential to serve as an effective learning medium for improving student retention in biology learning.

Abstract

This study aimed to analyze the effect of liquid organic fertilizer (LOF) derived from goat manure and banana peels, applied either individually or in combination, on the growth and yield of pakcoy (Brassica rapa L.) cultivated under a hydroponic system as an alternative to AB mix nutrient solution. The experiment employed a Randomized Block Design (RBD) with two treatment factors: goat manure LOF concentrations (0 ml, 30 ml, and 60 ml) and banana peel LOF concentrations (0 ml, 20 ml, and 30 ml). Observed parameters included number of leaves, plant height, leaf width, root length, and fresh weight. Data were analyzed using analysis of variance (ANOVA) followed by Duncan’s Multiple Range Test at a 5% significance level. The results indicated that the best single treatment was obtained with 30 ml of banana peel LOF at 4 weeks after planting (WAP). Furthermore, the combination of 60 ml goat manure LOF and 30 ml banana peel LOF (P2K2) produced the highest and significantly different results across all observed parameters at 4 WAP, particularly in leaf number, plant height, root length, and fresh weight. Therefore, the combined application of banana peel and goat manure LOF effectively enhanced the growth and yield of hydroponic pakcoy and has the potential to serve as a more economical and environmentally friendly alternative nutrient source in hydroponic cultivation systems.

Abstract

This research aims to inventory the types of plants used by the community as medicine in Rano village, Balaesang Tanjung sub-district, and their utilization as a learning medium. The type of research conducted is descriptive research with a qualitative approach. This research uses primary data obtained directly from interviews and field observations, employing a survey method with purposive sampling. Data collection techniques include observation, interviews with the community, and field observations. A shaman (sando) is a key figure who possesses knowledge about the use of medicinal plants. The research results show that there are 22 types of medicinal plants from 14 families used by the community to treat various diseases, including rheumatism, asthma, high blood pressure (hypertension), itching, scabies, cough, flu, and others. The parts of the plant that are used are the leaves, stem, fruit, roots, bark, shoots, sap, and all parts of the plant that are utilized. Methods of use include pounding, boiling, applying, and direct consumption. Thus, it can be concluded that the results of this study are suitable to be utilized as instructional media in the form of an e-book.

Abstract

This study aims to identify and describe the types of medicinal plants used by the community of Tindaki Village, South Parigi District, as well as to document their scientific names, morphological characteristics, parts used, and methods of processing. The research method used was descriptive with a qualitative approach through exploration techniques, direct observation in six hamlets, structured interviews with ten informants consisting of five key informants and five non-key informants, and field documentation. Species identification was carried out based on observations of morphological characteristics, including roots, stems, leaves, flowers, and fruits, and then verified using scientific literature to ensure the accuracy of the classification. The results of the study showed that there were 34 species of medicinal plants belonging to 23 families and 18 orders. The most widely used parts of the plants were the leaves and rhizomes, followed by the fruits, roots, stems, and sap. These plants are used to treat various diseases such as fever, cough, diarrhea, diabetes, hypertension, kidney stones, digestive disorders, and skin diseases. The conclusion of this study shows that Tindaki Village has a high diversity of medicinal plants that are still actively used, thus requiring continuous conservation and documentation efforts.

Abstract

This study aimed to determine the effects of light color and photoperiod on body coloration and growth performance of juvenile redclaw crayfish (Cherax quadricarinatus). A total of 144 juvenile crayfish were used in an experimental design consisting of six treatments based on two light colors (red and white LEDs) and three photoperiod regimes (6, 12, and 18 hours). The observed parameters included growth performance, survival rate, and changes in body coloration. The results showed that (1) red LED treatment with a 6-hour photoperiod produced the most optimal growth, whereas the 18-hour photoperiod treatment induced stress that led to reduced growth performance; (2) red LED treatments resulted in higher survival rates compared to white LED treatments; and (3) photoperiod significantly influenced changes in body coloration, with juveniles exhibiting blue and brown pigmentation. In conclusion, photoperiod affects the growth of juvenile crayfish, with red LED exposure for 6 hours representing the optimal condition. Differences in light color contribute to improved survival rates, while photoperiod plays a role in influencing body color changes.
